好人 我为我的基本英语提前道歉。 我的问题如下 我已经把一个gridview放在另一个手风琴里面的手风琴里面。 每个人都关联到一个objectdatasource。 现在，每个objectdatasource都有一个用于编写e.InputParameters的选择事件。 问题是我想写的参数之一是包含objectdatasource的项目的数据项。Objectdatasource
的obselected函数的ARGS是： BYVAL发件人作为对象，BYVALË作为System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs
的firstone是ObjectDataSourceView至极具有不是namingcontainer。而且我无法从ObjectDataSourceSelectingEventArgs中获取任何关于数据项的引用。
所以，我的问题在于如何获得objectdatasource的引用，包含它的项目或与特定项目关联的dataitem到我的“onselecting”函数中。
在此先感谢。
的VB是
Imports System.Data.SqlClient
Public Class WebForm2
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Protected Sub Page_lala(ByVal sender As Object, ByVal e As EventArgs) Handles Me.InitComplete
Accordion1.DataSourceID = ObjectDataSource1.UniqueID
Accordion1.DataBind()
End Sub
Protected Sub Accordion1_OnItemCommand(ByVal sender As Object, ByVal e As AjaxControlToolkit.AccordionCommandEventArgs) Handles Accordion1.ItemCommand
Dim Accordion2 As Control = e.Container.FindControl("Accordion2")
Dim objectDataSource As Control = e.Container.FindControl("ObjectDataSource2")
If Accordion1 IsNot Nothing And objectDataSource IsNot Nothing Then
AddHandler DirectCast(objectDataSource, ObjectDataSource).Selecting, AddressOf ObjectDataSource2_selecting
AddHandler DirectCast(Accordion2, AjaxControlToolkit.Accordion).ItemCommand, AddressOf Accordion2_ItemCommand
DirectCast(Accordion2, AjaxControlToolkit.Accordion).DataSourceID = DirectCast(objectDataSource, ObjectDataSource).ID
DirectCast(Accordion2, AjaxControlToolkit.Accordion).DataBind()
End If
End Sub
Protected Sub ObjectDataSource2_selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs)
Dim parameters(0) As SqlParameter
Dim dsv As ObjectDataSourceView = DirectCast(sender, ObjectDataSourceView)
parameters(0) = New SqlParameter("@cliente", "30697269610")
e.InputParameters("param") = parameters
End Sub
Protected Sub ObjectDataSource3_selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs)
Dim parameters(0) As SqlParameter
Dim dsv As ObjectDataSourceView = DirectCast(sender, ObjectDataSourceView)
parameters(0) = New SqlParameter("@documento", "FC0030-00040199")
e.InputParameters("param") = parameters
End Sub
Protected Sub Accordion2_ItemCommand(ByVal sender As Object, ByVal e As AjaxControlToolkit.AccordionCommandEventArgs) 'Handles Accordion2.ItemCommand
Dim gridview As Control = e.Container.FindControl("gridviewAplicaciones")
Dim objectDataSource As Control = e.Container.FindControl("ObjectDataSource3")
If gridview IsNot Nothing And objectDataSource IsNot Nothing Then
AddHandler DirectCast(objectDataSource, ObjectDataSource).Selecting, AddressOf ObjectDataSource3_selecting
DirectCast(gridview, GridView).DataSourceID = DirectCast(objectDataSource, ObjectDataSource).ID
DirectCast(gridview, GridView).DataBind()
End If
End Sub
End Class
